All-fiber highly efficient delivery of 2 kW laser over 2.45 km hollow-core fiber

Nature Communications
Anti-resonant hollow-core fibers have emerged as an important medium for high-power laser delivery due to their low optical nonlinearity and high damage threshold.

Ray-tracing analysis of crosstalk in multi-core polymer optical fibers

Optics Express, 2010
The aim of this paper is to present a new ray-tracing model which describes the propagation of light in multi-core polymer optical fibers (MCPOFs), taking into account the crosstalk among their cores. The new model overcomes many of the limitations of previous approaches allowing us to simulate MCPOFs of arbitrary designs.

Generalized Method to Describe the Propagation of Pulses in Classical and Specialty Optical Fibers

IEEE Photonics Journal, 2019
The comprehension of pulsed light propagation is of paramount importance in fiber optics. Here, we present a general method to describe the propagation of pulses in any kind of optical fiber, regardless of its fabrication process or constituent materials.

Modal Noise Mitigation through Fiber Agitation for Fiber-fed Radial Velocity Spectrographs

, 2018
Optical fiber modal noise is a limiting factor for high precision spectroscopy signal-to-noise in the near-infrared and visible. Unabated, especially when using highly coherent light sources for wavelength calibration, modal noise can induce radial ...
